It seems to me people are still having trouble with the part in which Brenda is holding Katjaa hostage. I will give you a step by step guide on how to do this part in one try.

1. Walk up the steps, and you will get your first dialogue. Alert Brenda of your presence by saying, "Yeah it's me."

2. Walk up to the screen door and open it. Don't take another step, or Brenda will shoot you.

3. When she points the gun at Katjaa, SLOWLY walk forward towards her. Once she says stop, immediately stop moving the left stick forward. Talk to her and then say, "It doesn't have to end like this."

4. When she points the gun at Katjaa, SLOWLY walk forward towards her. Once she says stop, immediately stop moving the left stick forward. Talk to her and then say, "Let her go, Brenda."

5. When she points the gun at Katjaa, SLOWLY walk forward towards her. Once she says stop, immediately stop moving the left stick forward. Talk to her and then say, "Please, don't make this any worse."

6. Once she backs up the stairs and has stopped, move towards her and then she will be grabbed by the zombie.

Now, for a walkthrough of the chapter.

1. Once you decided to let Dan live or kill him, walk out and examine the laser pointer of you saved Doug, or talk to the college kid and Carley. (Doug and the college kid will come also if you chose to save Doug.)

2. Then, follow the guide above until Kenny gets shot by Andy. Doug will provide some assistance with the laser pointer Fight Andy until he gets electrocuted by the fence. Just a bunch of button combos. Then you can either walk away or kill Andy.
